Benefits of technology

This patent relates to a gas inlet fixture that aims to improve flame quality and fuel efficiency in burners. The fixture is designed to center the gas nozzle in the middle of the burner tube, allowing gas to be injected down the middle. This results in a more symmetrical flame and better control over the fire. Overall, the fixture helps to maximize fuel efficiency and improve the performance of burners.

Problems solved by technology

This can result in decreased efficiency of fuel usage and impact the quality of the resultant flame.

Embodiment Construction

[0040]Set forth below is a description of what is currently believed to be the preferred embodiments or best representative examples of the inventions claimed. Future and present alternatives and modifications to the embodiments and preferred embodiments are contemplated. Any alternatives or modifications which make insubstantial changes in function, purpose, structure or result are intended to be covered by the claims of this parent.

[0041]The gas inlet fixtures 20 of the present inventions are used in conjunction with typical burner assemblies located in the cooking chamber or fire box of a gas barbecue grill to, among other things, improve flame quality and aid in the proper ignition of the flame. In the past, a variety of air shutters 10 have been used, including those shown in FIGS. 1A, 1B and 1C to, among other things, attach the burner tube 1 to the gas valves 8. As previously discussed, a gas manifold 7 distributes the gas to a number of gas control valves 8 that are usually ...

Abstract

A burner assembly including a gas inlet fixture for use with a burner tube, the gas inlet fixture including a plurality of tabs to engage a neck of a gas control valve to improve ignition and center the gas flow down the center of the burner tube.

Description

FIELD OF THE INVENTION[0001]The present inventions relate to burner tube assemblies for use on gas grills or other gas fired appliances. More particularly, the present inventions relate to burner tube gas inlet fixtures that are used to control the air-gas mixture going into burner tubes, provide positive contact with the gas control valve and / or center the gas flow into the center of the burner tube. The present inventions also provide burner tube gas inlet fixtures that may also function as air shutters.BACKGROUND OF THE INVENTION[0002]Burner tube assemblies, including those used in gas grills, are common in the art. A typical configuration of a burner assembly may be seen generally in FIG. 1A (see also U.S. Pat. No. 6,102,029, assigned to Weber-Stephen Products LLC). As shown, such an assembly typically includes a plurality of elongated hollow burner tubes 1, each burner tube 1 having a closed end 2, an open or inlet end 3, as well as a venturi region 4. A plurality of gas ports ...
